Spectral and dose dependence of ultraviolet radiation-induced immunosuppression.
Ultraviolet radiation (UV) wavelength and dose dependence has been demonstrated for a number of cutaneous endpoints such as erythema, pigment darkening, DNA damage, and photocarcinogenesis. More recently, a number of in-vitro and in-vivo models of UV immunosuppression have implicated UVA (320-400 nm) in immune protection as well as immune suppression. While the wavelength dependencies for immun...
متن کاملExpression of water channel proteins in Mesembryanthemum crystallinum.
We have characterized transcripts for nine major intrinsic proteins (MIPs), some of which function as water channels (aquaporins), from the ice plant Mesembryanthemum crystallinum. To determine the cellular distribution and expression of these MIPs, oligopeptide-based antibodies were generated against MIP-A, MIP-B, MIP-C, or MIP-F, which, according to sequence and functional characteristics, ar...
متن کاملPlant Growth and Photosynthetic Characteristics of Mesembryanthemum crystallinum Grown Aeroponically under Different Blue- and Red-LEDs
Mesembryanthemum crystallinum is a succulent, facultative crassulacean acid metabolism (CAM) plant. Plant growth and photosynthetic characteristics were studied when M. crystallinum plants were grown indoor under light emitting diodes (LED)-lighting with adequate water supply. Plants were cultured aeroponically for a 16-h photoperiod at an equal photosynthetic photon flux density of 350 μmol m-...
متن کاملMalate accumulation in different organs of Mesembryanthemum crystallinum L. following age-dependent or salinity-triggered CAM metabolism.
Different organs of Mesembryanthemum crystallinum exhibit differing levels of CAM (Crassulacean acid metabolism), identifiable by quantification of nocturnal malate accumulation. Shoots and also basal parts of young leaves were observed to accumulate high concentrations of malate. It was typically found in mature leaves and especially prominent in plants subjected to salt stress. Small amount o...
متن کاملImmunomodulatory effects of ethanol extract of germinated ice plant (Mesembryanthemum crystallinum)
The purpose of this study was to investigate the immunomodulatory activity of ice plant (Mesembryanthemum crystallinum) extract (IPE) in vitro and in vivo. Raji (a human B cell line) and Jurkat (a human T cell line) cells were treated with various doses of IPE and cell proliferation was measured by WST assay. Results showed that IPE promoted the proliferation of both Raji and Jurkat cells in a ...
